Hi Cezar,<br>
<br>
Your gaps are caused by not mosaicking the sets of images before running<br>
them through gdal2tiles. You'd need to use gdalmerge prior to gdal2tiles<br>
and be sure to set your no-data value in order to set the overlap rule.<br>
Otherwise what you get is the transparent values in one mosaic overwrite<br>
the values in the images below.<br>
<br>
Hope this helps,<br>
Best,<br>
Steve<br>
